| Research Abstract |
Experiments overexpressing or inhibiting chitinase in cultured macrophages revealed that chitinase increased CD36, ABCA1, and ABCG1 expression via PPARγ and LXRα pathway, promoted cholesterol uptake and Apo-AI dependent cholesterol efflux, and decreased inflammatory cytokines MCP-1 and TNFα expression by suppressing AP-1 transcriptional activity. Administration of chitinase inhibitor increased atherosclerotic lesion in ApoE knockout mice. These data suggest that chitinase has anti-atherosclerotic effects.
